Named craniodental and postcranial material from southern California was tested in morphology matrices; the broad analysis leaves nearby carnivoramorphan relationships unresolved, while a Paleogene-only subset recovers a caniform position outside crown Canoidea.

fossil-range · medium
Lycophocyon hutchisoni is bounded by holotype cranium UCMP 85202 and associated paratype skeletons from southern California within an approximately 46.2–42 Ma sample envelope; this is not a direct ancestry date or complete genus duration.
claim:taxon:lycophocyon:fossil-rangetaxonomy · medium
Tomiya's Paleogene-only morphology subset recovers Lycophocyon hutchisoni on the caniform branch outside crown Canoidea, whereas the broader analysis does not resolve its nearby carnivoramorphan relationships.
claim:taxon:lycophocyon:taxonomybiogeography · high
The named Lycophocyon material is reported from member C of the Santiago Formation in San Diego County, California; these localities do not establish a genus-wide North American distribution.

UCMP 85202 preserves craniodental material, while associated SDSNH specimens include cranial, mandibular and selected postcranial elements.
claim:taxon:lycophocyon:morphologyecology · medium
A six-variable discriminant classifier predicts carnivory for the holotype with 83% posterior probability, but this comparative model does not observe feeding, habitat, locomotion or an ecological guild.
